The Coulombs to Newtons Calculator is a tool used to calculate the electrostatic force between two charged objects based on Coulomb's Law. This force is measured in Newtons (N) and is determined by the amount of charge each object possesses and the distance between them. Coulomb’s Law quantifies how charged particles interact, which is essential in understanding electrostatic forces in various physical and engineering contexts, such as designing capacitors, understanding electric fields, and studying particle behavior.
This calculator is important for students, researchers, and engineers who need to compute the force between charged particles, whether for theoretical research, practical applications in electrical engineering, or experiments involving electrostatics.
Formula of Coulombs To Newtons Calculator
To calculate the electrostatic force in Newtons (N), you can use the following formula derived from Coulomb's Law:
F = k * |q1 * q2| / r²
Where:
- F is the electrostatic force in Newtons (N).
- k is Coulomb’s constant, approximately 8.988 × 10⁹ N·m²/C².
- q1 and q2 are the magnitudes of the two point charges in Coulombs (C).
- r is the distance between the charges in meters (m).
This formula calculates the force between two point charges based on their magnitudes and the distance separating them. The constant k is fundamental in determining the strength of the electrostatic force.

Example of Coulombs To Newtons Calculator
Let’s walk through an example to see how the Coulombs to Newtons Calculator works.
Suppose you have the following values:
- q1 = 2 × 10⁻⁶ C (Coulombs)
- q2 = 3 × 10⁻⁶ C (Coulombs)
- r = 0.5 m (meters)
Now, apply the formula:
F = k * |q1 * q2| / r²
Substitute the given values:
F = (8.988 × 10⁹ N·m²/C²) * |(2 × 10⁻⁶ C) * (3 × 10⁻⁶ C)| / (0.5 m)²
F = 0.2157 N
Thus, the electrostatic force (F) between the two charges is approximately 0.2157 Newtons (N).
Most Common FAQs
Coulomb’s constant (k) is a physical constant that is used in Coulomb's Law to calculate the electrostatic force between two point charges. The constant has a value of approximately 8.988 × 10⁹ N·m²/C² and is essential in determining the strength of the electrostatic force in a vacuum. It is fundamental to the calculation of forces between charges, making it a critical part of understanding electrostatic interactions.
The distance between two charges directly affects the electrostatic force between them. According to Coulomb's Law, the force is inversely proportional to the square of the distance (r²). This means that as the distance between the charges increases, the electrostatic force decreases exponentially. This relationship is crucial for understanding how charges interact over varying distances.
